Trying to set Caddy up as reverse proxy

[RedNo7 3]

Hi,

I have read a lot of posts from various websites and forums on how to do this, but I cannot get it to work for me.

- I have Emby running on a NAS (works perfectly internally)

- I have setup Caddy in a docker container on a RPi

- I have a domain with Namecheap

I have forwarded emby.my_domain.tld to my IP from Namecheap's advanced DNS tab:

Checking this is pointing correctly:

curl -s "https://cloudflare-dns.com/dns-query?name=<mydomain>&type=A" -H "accept: application/dns-json"

gives:

`{"Status":0,"TC":false,"RD":true,"RA":true,"AD":false,"CD":false,"Question":[{"name":"<mydomain>","type":1}],"Answer":[{"name":"<mydomain>","type":1,"TTL":1472,"data":"<correctIP>"}]}`

My docker compose for caddy:

services:
  caddy:
    image: caddy:2-alpine
    container_name: caddy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./caddy/caddyfile.json:/etc/caddy/Caddyfile
      - ./caddy/data:/data
      - ./caddy/config:/config
    environment:
      - TZ=Europe/London
    restart: unless-stopped

volumes:
  caddy_data:
  caddy_config:

My Caddyfile (IP is my NAS):

{
	<myemail>
}
<mydomain> {
	reverse_proxy 192.168.1.64:8096
}

I have port-forwarded :443 to :443 on my Pi.

My Caddy logs have two warnings
